Addition of two LnH bonds of an Yb II hydrido complex supported by bulky amidinate ligand to a CC bond lead to the formation of 1,2‐dianionic bibenzyl fragment (see picture). Both Yb II and hydrido centers are oxidized under the reaction conditions. The resulting Yb II ‐η 6 ‐arene interaction is surprisingly robust: the arene cannot be replaced from the metal coordination sphere when treated with Lewis bases.
